Lanolin

[catmandoo]

Understand that lanolin is the great antifoulant for props . Is this true , where does one get it,how best to apply and what pretreatment ?

 

[savageseadog]

It's the natural oil in sheeps wool, time to get chasing!

 

[tazzle]

Lanolin is the main ingredient in all those little pots of creme on SWMBO's dressing table - just swipe one (NB not the one that costs £120 / oz and hides wrinkles or the prop blades may start straightening or something)

 

[penultimate]

Lanolin (Hydrous Wool Fat BP) has a grease like consistency so it is necessary to warm the propellor blades before application.
Any chemist can obtain lanolin for you but it is not generally in stock because of lack of demand - allegedly. I paid £9 for 500g, enough to last me a lifetime and the hereafter.

Got mine from http://www.baldwins.co.uk/perl/go.pl/shop/adv-search-results.html
Smallest size will do. warm up lanolin and apply to polished prop, warm with gas torch to smooth off.

I applied lanolin last year on Amber. Used Lanocote (available in swindleries) and heated it with hot air gun as recommended to stop it washing off. Complete waste of time. Barnacles on prop in less than 3 months

It's also good stuff for putting on threads that you might want to undo in the future. eg rigging screws, engine coupling bolts etc. A commercial variety is called lanacote. Small tub lasts for years.

I also used it on the log paddle wheel. Worked a treat and it lasted 6 months before needing re-applying. The only thing that I have found that stops the log wheeel fouling up, and when heated (the lanolin that is) is easy to apply with a small brush.

A local chemist sold me a tub of Anhydrous Lanolin BP, 500ml for £6. Itrs used as a base for cosmetics.
Used for galvanised rigging screws and the prop. Polish the prop well and warm up with a hot air gun. Use a spatula to spread on the lanolin and then melt down with the gun. After it cools it should be waxy, not sticky.
My boat has been in the water (Argyll sea-loch) for two years and the prop is clean.

I've heard that indelible black marker pen ink applied to the prop(s) will keep barnacle away for a reasonable time.
Any one used?

Try Ambassador Marine - they sell lanolin under the trade name Henley's Propellor Protector.

LOL. Against better judgement (why would grease stay on a prop when specially formulated paint doesn't).
Well guess what. It does not stay on. Goes off in no time and is a total waste of time.
Using it for metal fitting which need to be undone as another post suggests?
You gotta be kidding. I faithfully used it liberally before I put my prop on.
I year later the yard used heavy hydraulic equipment to get it off again (they thouht I used super glue or a TIG welder installing the prop the year before).
Grease stuff above the waterline? Yeah right. I needed 1 liter of Acetone to clean the solidified gop out of the tracks of a sliding door.
Do not forget the stuff was invented by god to keep sheeps fur and skin dry in the winter drizzle.
And that's were it belongs, on sheeps and not on ships.
Another urban legend exposed.
